2013 Ritchey Logic P-275 steel hardtail 650B mountain bike

Ritchey’s even quick to develop his 27.5″ / 650B platforms, first showing a tandem 650B breakaway folding bike at NAHBS this year, and now unveiling the P-275 steel hardtail.

The frame looks similar to the P-29er but has several key differences. Tom Ritchey being Tom Ritchey, all tubing profiles and geometry were noodled with to get the ride just right for the mid-sized wheels.

And, because they can develop the bike as a system with all of the components from their warehouse, making it stiff where it needs to be while still keeping the lively ride that steel is known for.

Ritchey Logic WCS carbon rigid 650B 275 fork and wheels and tires

The 650B carbon fork, wheels and tires all had to be developed to go with the bike.

Fork is full carbon (including QR dropouts) and comes in at 615g with a straight steerer. Retail on its own will be $499, and they may add a tapered model next year. Wheels are the alloy Vantage II and are tubeless ready with tubeless run strips pre-installed and valve stems included. Inside width is 20mm. Wheelset weight is claimed at. 1587g with standard QR rear and 15mm thru axle. Tires will be available in WCS level only for the Shield tread pattern in a 27.5×2.1. Weight is 533g.

These items should be available in November.

They’ll include their QR axle to run them in QR forks.

The seatstays were able to remain thin for compliance since they didn’t new to be reinforced to handle braking loads. The bend is to clear the caliper.

Ritchey didn’t have a flood of demand for the sliding dropouts of the P-29er, shown at bottom, so they made this one for geared drivetrains only. Dropout isn’t replaceable since “it isn’t as big of a deal on a steel bike.” Having owned an old steel Bianchi hardtail, I can say that you can bend a steel hanger back into shape many, many times without issue.

It uses their integrated headtube with completely hidden lower bearings.

17″ complete bike weight with their new WCS Paradigm pedals is 21lb 3oz. Frame will be available in odd sizing from 15″ through 21″. Retail will be $1,100 for the frame, no framesets or complete bikes are offered.

Visual comparison of the P-29er’s sliding dropouts (foreground).


  1. So they missed out on the 29″ game by never really getting in it to begin with, but are happy to jump in on this new platform pretty darn quickly.

  2. That paint job is sweet. Refreshing departure from the black/red/white that’s been pretty dominant for the past few years. May compel me to buy a mountain bike.

  3. what do they mean by “no framesets or complete bikes are offered”?
    im confused; how do i get this bike if they don’t sell the frame or the complete bike?
    maybe im missing something

  4. @fuzzy Tom Ritchey didn’t “jump in on this new platform pretty quickly.” He was making 650B bikes over 30 years ago.
    And FYI, 650B isn’t new.It’s been around for more than half a century.

  5. @ fuzzy:

    Actually Ritchey made a 29er back before they were calling them 29ers. It was called the Mt. Cross. To the untrained eye it looked like a cyclocross frame but the geometry was totally different and it had more clearance. I had one and with 700×37 WCS tires it absolutely flew, especially on the “trails” in the SF Bay Area (which are really more fire roads). True, it wouldn’t take 2.2″ tires but at the time 700×2.2″ tires really didn’t exist.

  6. I will be riding one of these!

    Yippa, Tom and Joe have been using those dropouts since the ’80s (maybe longer). I’ve heard them called Logic drop outs, Breeze-In drop outs, T&J’s, and Breezers. They, as well as others, use them because they provide more area to weld the stays to the drop out.

    Unlike Feg and Clyde, I’m glad that the sliding drop outs are gone.

    Its good to see Tom and Joe (via Fuji) back in the frame business!

  7. Ha! 29 years after I built a bunch of Ritchey’s first frame sets up with 650B wheels he’s at it again…
    I had one of the first Woodsie Bike frames commissioned by John Scott of Davis, CA. Tom built them with Columbus road tubing, they were light as hell. Of all the bikes I’ve ever owned I miss that one the most….moo

  8. I agree, I hate sliding drop outs. They are for the wishy washy. If you want a single, build one. Otherwise, nice breeze style drops are perfect.

  9. How to I buy a complete bike in 17″ frame as shown? Need 1 for New England trails to show off! Had my Schwinn Paramount 90 series, Bridgestone MB-0 Zip, Fat Chance Buck Shaver, and Klein Attitude. Now hitting 45 I need odd school name and quality with 650 B riding… Let me know please..
